Electric car concept is based on the Renault Kangoo Be-Bop and is still a one-of-a-kind, handcrafted vehicle featuring Acid Green windows and solar panels mounted on the roof.

Renault has let one of its most treasured futuristic creations, the Z.E. Concept (which stands for zero emissions) run loose at the Goodwood Festival of Speed at the Silverstone race track in the UK last weekend.

The Z.E. is an electric vehicle based on the Renault Kangoo Be-Bop. Renault put the 2 million pound car (about 2.3 million euros) out on the track along with a couple of other rarities from the French carmaker's museum in Paris - an Ondelios and a 1959 electric Dauphine.

The rather pricey Z.E. Concept is a one-of its kind, hand-crafted fully-electric vehicle. It features Acid Green-colored windows and solar panels on the roof. At the event, the Z.E. took a ride up Goodwood Hill and mingled with company such as a Jaguar XJ13 and an Aston Martin DBR1.

The Festival of Speed is a 3-day event which took place at the Goodwood House, West Sussex, England between the 3rd and 5th of July.

Renault first unveiled the Z.E. Concept at the Paris motor show in 2008.
